It looks like none of these devices are as big as the current Cyclone V -A9 device. They are all somewhat smaller.

The bright spot is that "2x higher performance for up to half the cost" is claimed. Now, do you think they meant 2x performance, or actually 2x HIGHER performance? I'm hoping for the latter, which is 3x performance. Either way, it could run Prop2 at 160MHz, which is full speed.

Strange combination, the GX family looks a new high end design (M20K, 10G tranceivers, floating point, fractional PLL, Mlab etc) while the LP family looks lik new Cyclone IV member, lacking most of the new features of the Cyclone V family, even going back to M9K

As Chip mentions above, many of these Cyclone 10's are smaller than the P2 123 FPGA, and there are many choices already for partial P2 emulation. (ie less than 16 COGS)

Also, you often find Eval boards come on stream before you can buy FPGAs, and the Speed files come before that.

P2 123 allows full P2 emulation, so that is not going away.

When a C-10 series speed file is available (might be now, if you ask Altera nicely), you can see what MHz a C-10 allows.
Then, if that reports significantly faster MHz, you could try to get a C-10 Eval Board, to test P2 at a higher MHz.

These smaller C-10's, may have more potential running P1V code.

Another part Parallax could look seriously at, for P1V, is the Lattice ICE40UP5K-SG48ITR ~ $6.00
( has an Eval board iCE40UP5K-B-EVN $65)
